Most diamonds give a yield of 40 to 45 percent from rough to polished stone using current methods. Sometimes as much as 70 percent of a diamond is lost during the cutting and polishing process, but the price can jump six fold. The 1977 price for colorless 2½ carat rough was US$750. A flawless one carat stone can fetch as much as US$20,000.

There are five main steps in cutting a diamond: Planning – An expert will carefully plan how the diamond will be cut using computers and the latest technology. Cleaving – This is the process where diamonds are used to cut one diamond into multiple pieces. Bruiting – This step is where the diamond is shaped into a specific cut.
10 Polishing of diamond Processing the hardest bulk material is not trivial. To date most methods still rely on diamond to process diamond. The {111} plane of diamond is substantially harder and more wear resistant than the others. Lapping Rough processing of diamond is achieved using lapidary processes with a diamond
